SubSwap

I built SubSwap because every "what to use instead of X" article I'd ever read gave me a list of substitutes but never the actual amount. So I'd guess. And the recipe would come out fine, or weird, or worse than the original, and I'd never know which substitute was actually meant to work in that quantity.

SubSwap is a calculator. Type the ingredient you're missing, the amount, and the unit. It gives you the exact substitute and the exact ratio. 1,135 ingredients, 4,000+ swaps, free, no signup.
